EXCAVATOR AND SELF-LOADING CONVEYER.

SPECIFICATION forming part-of Letters Patent N0.-376,708, dated January 17, 1888.

Application filed April 12, 1887.

To all whom it may. concern:

Be it known that I, JOHN CABLE, of Cable, in the county of Sherburne and State of Minnesota, have invented certain new and useful Improvements in Excavators and Self-Loading Oonveyers, of which the following is a specification, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature and Object of my invention will be fully set forth in the following specification and claims.

In the drawings, Figure 1 is a plan view; Fig. 2, a side elevation; Fig. 3, a vertical lon- 5 gitudinal section, and Fig. 4. a detached detail. 7

Similar letters of reference indicate. similar parts in the respective figures.

Ais the frame of the machine, to the front of which is attached, in any well-known manner, the pole a. The rear part of the frame is formed into two arms, b b, which serve to support the drivers seat B, and also as rests or catches for two levers, as will be hereinafter described. Y Y On the inner side of theframe A, and on each side of the machine, is secured, at aright angle to the frame, a bar, 0, extending above and below the frame. These bars Care en- 0 larged at c to permit the axle D to pass through them, and thus form the bearing or'support for the frame of the machine. Y 011 each side of the machine a bent arm, F, is bolted to the upper part of the bar 0 and 5- also to the frame A, extending a short distance below the frame. A'rod, f, is loosely mounted in these arms'below the frame A,and rigidly attached to thisrod f is a platform, f, which servesas afoot-rest for the driver. The plat- 40 form is held up by means of the lever which is bent so as to rest on one of the arms I) of the frame A. Ateach end of the rod f is an arm,

f to which arms are attached the brake-shoes 'f WVhen it is required to apply the brakes,

5 it is onlynecessary to disengage the leverf from the arm I), when the platform will drop down and the driver can apply the necessary force with his feet.

A hopper formed of two sections, E E, is

5 0 supported in the following manner: The section E is sustained by the axle D and adapted to be revolved thereon. The section E, which purpose ofgiving play to the elevating mechtwo sprocket-wheels, O.

which it would have a tendency to do while being filled. lhe section E has aninclined bottom, and is made slightly smallerthan'the section E, so as to fit within it, but isprevented from entering too far by means'of lugs e on the inner faces of the sides of section E. The'section E is held in contact with the section E by meansof an angle-bar, e, mounted ff on the rod f, and can be operated by the foot of the driver. A lever, G, is pivoted to the a side of the section E at g, the short arm of the lever coming in contact with a pin, 9, on the side of said section. This lever is for the purpose of tilting the section E when the contents of the hopperare to be. discharged. l H is a leveler, which extends across the maf chine at its rear and is hingedto the lower. ends of the bars .0 by means of the rodsh. 5 This leveler can belifted up and secured,when not in use, by meansof the lever h, which passes up through the platform f, and is bent I to engage with one of the arms b of the frame A, thus being under the control of the driver;

I is a plate, of steel or other suitable metal, having its sides flanged, and being provided with a hook atthe top of each flange to 1 engage with the'top of the hopper when in use. To the lower end of the plate I are bolted, one to each flange, two plow-beams, k k, to which is attached the plow K. A draft evener, J,'is secured to the plow-beams k, to which thehorses are hitched, both for the purpose ofplowing and conveying.

L L are bent arms pivoted,one on each side of the machine, on the axle D. A shaft, M,is; mounted in these arms, having a. bearing on the bottom of the slot m. This slot isfforthe anism-in case any large lumps should get between the plate'I and the scrapers, to be hereinafter described. 'lhefshaft M extends beyond the arms L, and on eachof its ends is mounted a sprocket-wheel, IN. On the same shaft, but inside'ofthe arms- L, are mounted P P are bars supported on the shaft M by r means of boxes bolted on them; Theupperi ends of these bars are connected by means of the shaft 1), on which are mounted the sprocket-wheels p p and p p". The lower ends of the bars are drawn down and screw-threaded, and are connected by means of the rod 19 through which they pass. The rod 19 which is rectangular, is rounded at its ends to form a journal for the sprocket-wheels p.

Q Q are the draft-wheels, and R It sprocketet-wheels loosely mounted on the hubs of the wheels Q Q, each of said sprocket-wheels being provided with a clutch, q, adapted to engage with a similar clutch on the hub of one of the wheels Q. The engagement or disengagement can be made in any well known manner.

Chains S S pass over the sprocket-wheels N and R,and constitute the main drivingchains.

T T are chains which pass over the sprocket-wheels O and p.

U U are chains which pass over the wheels I p and p. The tension of these chains U can gle-bar, i, the ends of which rest on the frame A and are journaled in the arms L L. Attached to this angle-bar 2', close to the bend at each end, are chains z" i, which pass over a sheave, Z,at the top of each of the arms L. The chains 1" t" are attached to reels Z on a shaft, Z, having hearings in the frame A at its rear end. The chains t" t" are adapted to be wound upon the reels Z.

To the plate I is attached another bar, V, to each end of which is secured a chain, a. The said chain passes under a sheave, a, on the lower end of the bar 0, and is secured to the shaft Z on which itis adapted to be wound. The shaft Z is provided with a crank and with a ratchet-and-pawl mechanism of ordinary construction. 7

The operation of the machine is as follows: Supposing the plow and elevating mechanism to be in the position shown in Fig. 3, the machine is started, and, the sprocket-wheels It being thrown in gear with the draft-wheels Q, motion will be imparted to the chains U U and scrapers u, in the direction indicated by the arrow, through the medium of the chains S and T, which will move in the direction indicated by their arrows. As the earth is loos ened by the plow it will be forced up the inclined face of said plow until it is caught by the scrapers and carried up the inclined plate I and dumped into the hopper. WVhen the hopper is sufficiently full,the machine must be stopped. Now, by winding the shaft P, the chains i'will be wound on their reels, and the plate I, and with it the plow, lifted up independently of the elevating mechanism until the angle-bar 2 causes said plate I to j am with the elevating mechanism, when the arms L will be lifted and will carry with them the plate I, the plow, and the elevating mechanism. At the same time the chain a will be wound on the shaft Z and thus draw the bottom of the plate and also the plow and the elevating mechanism back toward the hopper until they will be in the position shown in Fig. 2, the ratchet-andpawl mechanism on the shaft 1 serving to securely'hold them in such position.

It will be seen that the chains 1; have a longer distance to travel than the chains 1), and the travel in the same time is accomplished by winding the chains ion reels which have diameters greater than that of the shaft 1*, on which the chains 12 are wound.

In order to discharge the contents of the hopper, the anglebar c, is thrown out of contact with the section E,when the weight of the dirt will force it back, and by pressing on the lever G the section E can be tilted sufliciently to discharge all its contents. By securing the lever G to the section E in the manner described, it will be seen that it is necessary only to use the lever until the equilibrium of the section E is overcome, when it will swing forward of its own momentum and independently of the lever, the long arm of which will rest on the leveler II, as shown in Fig. 3. The object and manner of operating the brakes and the leveler are obvious and need no further description here.

Having described my invention, I claim- 1. In an excavator and self-loading oonveyer, a hopper in two sections, a plate having a plow attached thereto, and scrapers adapted to carry dirt up said plate, combined with sprocketwheels mounted on the hubs of the draft-wheels, and adapted to engage therewith by means of a clutch mechanism, and asystem of sprocket- I wheels and chains for imparting motion to said scrapers, substantially as described.
